So a few months ago, my ethernet port on my motherboard stopped working, but everything else is working 100%, so I ended up ordering a pci ethernet card. http://www.newegg.com/Product/Product.aspx?Item=9SIA24G1XA5134 is the product that I ordered. I installed it in both of my available PCI slots, and the led works when I try to plug my ethernet cord into it; however, I can never get connectivity, and my pc says that an ethernet cable is not plugged up. It doesn't show up in my network adapters either. Any thoughts?
